Tension rod systems, cable tension members and cable meshes
Tension rod systems and cable tension members are used, for example, for trusses, suspensions, cross bracing and wind bracing, particularly in engineering works (new structures) but also in the repair or strengthening of existing structures.
Cable meshes offer a wide variety of applications. For example, they can be utilised as design elements on facades or in buildings for transparent room partitioning. Cable meshes can also be used as fall protection for people or vehicles.
Regulatory framework
DIBt grants national technical approvals (abZ) for tension rod systems, cable tension members and cable meshes. European Technical Assessments (ETAs) can also be issued for these products.
Furthermore, DIBt grants general construction technique permits (aBG) for construction techniques comprising these products for which there are no conclusive technical rules.
Please also refer to the applicable design and execution rules, cf., in particular, MVV TB, Parts A 1 and A 2.
For fall protection meshes, please also note the ETB Guideline on fall prevention components (Bauteile, die gegen Absturz sichern), June 1985, IfBt Mitteilungen, vol. 2/1987.
National procedure
To prepare an abZ/aBG for your construction product, we need an application from you. We recommend that you contact us prior to doing so. Feel free to send us your enquiry informally via email to dibt(at)dibt(.)de or to the competent technical contact listed in the top right.
For a first assessment, please send us the following information:
- Description of the construction product and its intended field of use
- e.g. material, configuration, number of sizes, variants, dimensions
- e.g. use in walls, ceilings, interior construction, building services
- Description of the construction technique and its field of application
- e.g. design of walls, ceilings, elements, etc., and interaction of components
- e.g. application in foundation engineering, reinforced concrete construction, building insulation; as load-bearing or non-load-bearing component; under static and quasi-static loading; fire exposure; other environmental exposures
- Information regarding impact on regulatory concerns
- in particular structural integrity, fire protection, health and environment protection, sound insulation as well as thermal performance
- Explanation of need for an abZ/aBG
- Do you significantly deviate from the Technical Building Rules?
- Or do neither Technical Building Rules nor generally recognised technical rules exist?
- Contact details
- preferably email address and/or telephone number, as well as name, organisation/company, and postal address
We will then contact you to clarify the next steps.
If you already hold a DIBt approval and/or construction technique permit and wish to apply for an amendment, supplement, or renewal, please use the form provided below.

European Technical Assessment (ETA)
To start the ETA procedure, please submit the form below. We will then check if the prerequisites for issuing an ETA are met, i.e., in particular, if the product is not fully covered by an existing harmonised standard. If the prerequisites are met, we will check whether a European Assessment Document (EAD) covering the requested assessment scope already exists or still needs to be developed. If an EAD needs to be developed or amended, a complete technical file needs to be established before the procedure can begin.
